Here's how it works:

* Phagocytes are a type of white blood cell that engulf and destroy harmful invaders like bacteria, viruses, and parasites.

* The process is called phagocytosis, where the phagocyte surrounds the microorganism and engulfs it into a vesicle called a phagosome.

* Once inside the phagosome, the microorganism is broken down by powerful enzymes and other chemicals.

There are different types of phagocytes, including:

* Neutrophils: The most common type, they quickly arrive at the site of infection.

* Macrophages: They are larger and live longer, patrolling tissues and engulfing debris and pathogens.

Phagocytes are crucial for the immune system's ability to fight off infections.
